client library - cant detect disconnection

I use processings client library.

it works very well, but i cant detect disconnection.

I cant make a 'keep-alive' connection.

When client disconnects; i want to try reconnect again..

Pls help.

Thank You.

import processing.net.*;

void setup() {

size(1024, 768);

background(255);

smooth();

k1ip = "127.0.0.1";

k2ip = "127.0.0.1";

k1Client = new Client(this, k1ip, 7000);

k2Client = new Client(this, k2ip, 7001);

}

void draw() {

if (k1Client.available() > 0) {

dataIn = k1Client.readBytes();
